Grenoble grenade attack injures 12, six critically
At least 12 people were injured, six of them critically, after a grenade attack on a bar in the French city of Grenoble, AFP reports.

The explosion occurred on Wednesday evening, shortly after 8:00 p.m. local time (7:00 p.m. GMT), in a neighborhood in the southern part of Grenoble known as the Olympic City.
The attacker entered the crowded bar and threw the grenade without giving any warning.
Investigators have yet to identify a motive but do not believe it was a terrorist attack, though they have not completely ruled out this possibility.
French authorities reported that the suspect appeared to be carrying a Kalashnikov assault rifle but did not use it.
The Grenoble hospital has implemented an emergency plan to treat the wounded, said the city's ecologist mayor, Eric Piolle, who condemned the act, calling it "a criminal act of unprecedented violence."
